WhatsApp Echo Bot: Automate Instant Message Replies
detail.loadingPreview
This n8n workflow provides a simple yet powerful solution to automate WhatsApp message responses. It handles Meta's webhook verification and instantly echoes back any incoming text message, perfect for testing or basic engagement.
About This Workflow
This n8n workflow sets up a robust system for interacting with the WhatsApp Business API. It cleverly uses a single webhook URL to manage both Meta's required webhook verification process (GET request) and the main message receiving stream (POST request). Upon receiving a WhatsApp message, the workflow intelligently identifies the message content and automatically sends an "echo" reply back to the sender. This powerful template is ideal for developers testing new WhatsApp integrations, creating a basic auto-responder, or simply demonstrating the immediate capabilities of n8n in conversational AI without complex logic.

- Automatic Message Detection: Intelligently identifies and extracts user messages from incoming WhatsApp notifications.
- Instant Echo Reply: Automatically sends the received text message back to the sender, providing immediate feedback.
- WhatsApp Business API Integration: Connects directly to your WhatsApp Business Account for sending and receiving messages.
